基于最大升阻比的制导炸弹弹道设计方法

摘要

According to the characteristics of guided bomb unpowered flight and most of the methods of increas-ing range has large calculation,a glide traj ectory of the guided bomb was established,and the glide traj ectory was based on maximum lift-drag-ratio.The attack angle was adj usted by controlling the rudder angle,and the upward lift was produced to achieve extended range.The simulation results showed that:the design of guided bomb based on maximum lift-drag ratio had less calculation,extended range was remarkable,which was three times more than the average range of conventional bombs.%针对制导炸弹无动力飞行特点和多数增程方法计算量大的问题，提出了基于最大升阻比的制导炸弹弹道设计方法。该方法通过控制俯仰舵偏角来调节攻角的大小，使弹体产生向上的升力从而实现增程。仿真结果表明：采用最大升阻比法设计的滑翔增程弹道计算量小，增程效果显著，制导炸弹射程是常规航空炸弹的3倍。
